Yes, it is possible to add an authorized user to a Diners Club account. An authorized user allows another individual to make purchases using your account, which can be a convenient option for family members or trusted friends. While the primary cardholder is responsible for all charges made by authorized users, this arrangement might offer flexibility for shared expenses. The process typically involves logging into the account online and providing the required information for the person you wish to add. Additionally, the policies regarding the number of authorized users and any applicable fees can vary, so it is always a good idea to check the latest information on the Diners Club website. They will have the most accurate and updated details regarding adding authorized users to your account.
